Got the letter and checked with what appears to be the new Premiermiles hotline (2860 0372 (replacing 2860 0360)).

Premiermiles CS confirmed the minimum holding period will not reset as a result of this migration.

Well it's nice to get higher priority to CS.

I also had a look at the Notice of Amendment. It appears to change a lot of names only for now. One curious change is replacing "Worldperks" (which is the contractual name for Premiermiles points) to "SkyMiles" - I hope we are not reduced to redeeming Delta Skypesos under the Premiermiles VS card!

So Citibank is going to send a new card to us? I wonder if this is meant to be an upgrade for all existing PremierMiles card holders or just for selected customers. I myself have not received the letter yet.
To me, the only interesting thing is that this will be the first Visa Signature card for Hong Kong... making it a bit "special"... somehow
